How Masks in an Image Allows the User to Achieve all Sorts of Effects

Image masking is the process of hiding or showing parts of an image or object. It is used to create various visual effects and is often considered a powerful tool for visual advertising campaigns. The most common masking technique found in everyday images is the layer masking technique.

Types of Image Masking Service:

Layer masking allows the user to change the opacity (transparency) of specific layers, so you can control how much of the bottom layers show on the top layer and how deep the image appears. Layer masking takes advantage of the multiple layer options in Photoshop and allows you to create an innovative news image from a collective of separate images. Here the images in each layer a masked separately so that only parts of the bottom layers appear of the top.

Vector masks however doesn’t require the uses of multiple layer masking, although multiple layer masks can still be used. Vector masks limit the visible parts of a layer through the use of vector paths. Unlike traditional pixel-based layer masks, which can be soft, blurred or partially transparent, vector masks defines a fully opaque visible area bounded by a hard edge, so the image is always clear.

Masking Technique:

Another masking technique is the Quick mask, although it’s not commonly used by Photoshop users, It does have its advantages. The Quick Mask appears as an entry in the Channels panel rather than to a specific layer. Capable of being edited just like a layer mask, a Quick Mask provides a temporary pixel-based visualization of a selection, which appears as a colored mask unlike the “running ants” or outlines lines in the layers masking options. It’s a fast and easy solution to get masks done quickly.

Adjustment Layer Masks are Identical to image-layer masks in every respect except that the layer type to which they’re applied. Adjustment layer masks define which image areas are and aren’t affected by an individual adjustment, this extends to levels, brightness, contrast and many other aspects of an image. Adjustment layer mask technique is also known as advanced layer masking, as this type of masking extends to the functionality of adjustment layers, this allows for specific color corrections to specific parts of an image.

All of these techniques and functions serve as clipping masks. Photoshop allows a user to create either a layer mask or a vector mask, which can be applied to both the base layer and the layers above it. Designating one of these Masks in an Image allows the user to achieve all sorts of effects.
